创建表MySql时出错 - （错误号：150）

Question

我对此脚本有疑问。有人能帮助我吗？

ERROR 1005: Can't create table 'db_new.users_roles' (errno: 150)
SQL Statement:
CREATE TABLE `luxury`.`users_roles` (
  `id` INT NOT NULL AUTO_INCREMENT,
  PRIMARY KEY (`id`))

在数据库中有表格＆＃34;用户＆＃34;和＃34;角色＆＃34;。 ＆＃34; users_roles＆＃34;是ManyToMany Hibernate的表格

Answer 1

尝试这样一次，

CREATE TABLE IF NOT EXISTS `users_roles` (
  `id` int(12) NOT NULL AUTO_INCREMENT,
  PRIMARY KEY (`id`)
) ENGINE=InnoDB DEFAULT CHARSET=latin1 AUTO_INCREMENT=1 ;

Answer 2

也许尝试以下

检查用户的所有权限。

select user,host from mysql.user;

找到授予特定MySQL帐户的权限：

show grants for 'root'@'%';

分析你的表

analyze table luxury

优化

optimize table luxury

再次运行脚本
